amazing. I wish I had all wheel drive, and Lap 3! Hey, is that full interior and spare tire, etc, or is all that stripped out. Impressive stuff either way.

Maybe I should weigh down the rear to try to get some traction, LOL! you can catch a lot of folks off guard with that kind of 0-60.

Hey there, just wondering, but in your modification list I don’t see anything about using the Pro-Tuner, I reached out about it being a requirement and was told to “sell the JB4” but it seems like you’re using it to make modifications to the LAP3 tune still?
Can you comment more on the Lozic TCU vs LAP3? I currently have Lozic Pressure3 and curious if a Stage3 LAP3 is worth the upgrade
I have the WMI , EWG, and Fuel-it and don’t want it to be wasted money

I don't have the pro tuner. I don't use WMI. I run CPI (charge pipe injection) from BMS. I use JB4 to control the CPI and for logging. I don't have the EWG or fuel wires attached or boost added etc. Just use it for CPI. You can continue to use JB4 for your WMI when using the lap 3 ECU
I am only stage 2 TCU from LAP3. Its not as aggressive as the LOZIC pressure 3 or the LAP3 stage 3. It is quicker than stock though.

Looks like you will be the first 10 Second G70 in the world. It's so close!
Hopefully today!

First impression LAP3 ECU, 2.5 with CPI
Upon the LAP3 box arriving I immediately began pulling out the old ECU along with it's bracket. It is a very simple job with a 10mm socket and some extensions. Once I had the LAP3 2.5 ECU installed I stepped inside the car in order to turn it on. I had to start it up about 4 times before it finally came to life. The smell of the built up fuel was horrible. I took it for a drive to my local E85 gas station in order to fill up with a E50 mix. I drove around for 20 mins or so in order to let the ECU do some learning and adaptations. When I 1st went WOT the car picked up immediately and with a surge in power, I was very impressed. I had a couple of hickups in terms of the correct settings for CPI in the JB4 but once I got those straitened out everything worked flawlessly.
-The shifts driving around normally are very smooth and now the throttle seems very linear in comfort.
-The extra timing makes the top end of the car at 6k RPM come alive.
-Torque seems to come on faster right at the beginning and stays smooth.
-In manual I even get some pops in comfort when downshifting.
-I ran some logs on the JB4 and AFR is buttery smooth, along with boost and timing.
-No problem at all with HPFP, stayed at 10-11 even while running E50 which the most I was able to do on jb4 was E45.
-On JB4 my most aggressive Map6 would only be useful if I wanted to really go fast but it wasn't practical for daily driving because of the hpfp crashes on E45.
-looking forward to trying out even higher ethanol mixes to see how far it'll go.
Previously I was on JB4 with CPI matches with a Lozic TCU. My best 60-130 jb4 run on map6 on E45 was a 9.27. Now with the LAP3 2.5 tune I was able to run a 60-130 in 8.40 seconds. This is with full interior and OEM wheels. I was never able to even brake into the 8s with just the JB4.
Now to review the extras. The disabled ISG (Idle Stop and Go) is very nice and allows me to forget about pressing that darn button every time I turn the car on. I chose to have the pops set up for sport mode only and with my current X-Force exhaust set up and OEM primary cats I think they sound good and aren't too loud. So far the logs look very clean and I am more than pleased with the regular drivability and performance that this tune provides.
For whoever wants the best ECU tune on the market for our platform look no further you've found it.
Wanted to thank David Chung for the quick communication and answering all my questions. Also big thanks to Charlie @Cashby31 for helping me set up the correct CPI settings in the JB4.

Lap3 Stage 2.5 ECU and Stage 2 TCU review updates.
After 2 months of recovering from surgery, I took the car out for some testing. Set the Dragy record for #1 1/4 mile time at 10.93. Also improved my 0-60, 60-130 and 0-130 times.
Two days later, I took the car to the track to see if the dragy was correct.
I had multiple 10.9x slips with the best being 10.958, taking the spot for the quickest AWD stinger.
What’s interesting is that if you look at the quickest cars, I’m the fastest daily driver stinger that has not experienced a major issue after hitting a 10 second run nor am I a shop car or a sponsored driver. Just a normal guy that knows little of tuning, slapped in the ECU, TCU and WMI and pressed the gas!
If you are looking for a reliable tune that you can install and not need to worry about overboosting, new revisions, or blowing your head gasket, this is the tuning solution for you!

I've seen some claim to be using E60-E70 with LAP 3 tune + CPI? Is full E85 possible with Lap 3 + CPI?

OEM ECU fueling crashes at E40-E45 even with CPI. @Avant has been able to use up to E75 with our ECU tune & CPI.
